2 Claims. (01. 84-422) My cinvention; as describedwhereim and-',.i1.1us.-. I.

trated in the. accompanyin drawings n ist 10.1., '1

a drum pedal, an object of which is to provide means for alternate heeland toe action of the drummer.

Another object of my invention is to provide a drum beating actionthrough which alternate beats are accomplished by alternate leg musclesof the operator, thus overcoming leg strain and fatigue.

A further object of this invention is to provide a beater operatingpedal action mechanism controlled through alternate heel and toemovement of a drummer.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings inwhich:

Figure l is a side elevational view of my action,

Figure 2 is a similar view action,

Figure 3 is a front elevational view of the device, and

Figure 4 is a broken away front elevational view of a modification.

While one embodiment of my invention is illustrated in the abovereferred to drawings, it is to be understood that they are merely forthe purpose of illustration and that various changes in construction maybe resorted to in the course of manufacture in order that the inventionmay be utilized to the best advantage according to circumstances whichmay arise, without in any way departing from the spirit and intention ofmy device, which is to be limited only in accordance with the appendedclaims. And while I have stated the primary field of utility of myinvention it remains obvious that it may be employed in any othercapacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, thesame reference characters are used to designate the same parts andelements throughout and in which l0, refers to my invention, and H,indicates a bass drum to the rim l2, of which is attached by a clamp l4,the base l5, of a frame 16, provided with fulcrums l1 and I8, to whichis pivotal-connected the depending ears l9 and 20, of a pedal 2|, havinga heel rest 22.

To the forward or toe end 23, of the pedal 2|, is pivotally connected at24, the right angular lower end 25, of a link rod 26, the upper angularend 21, of which is pivotally connected in one of a series of apertures28, of a lever 29, which is pedal illustrating a different fixed toatransverseshaft 30, pivotally supported 4 in the upper-ends 3-l and 32,of the upright arms-- 33 and 34, of the inverted U-shaped member 35, offrame it. To the arm 33, is connected a bracket 36, to which is securedone end 31, of a coil spring 38, the other end of which is secured tothe shaft 39, whereby the shaft is held in a normal position.

Secured to the outer ends 39 and 40, of the shaft 39, are the lever arms4| and 42, of heaters 43 and 44, the former being upright and the latterdownright, whereby when the heel end 44, of pedal 2i, is pressed down(as shown in Figure l) the link 26, raises lever 29, and rotates shaft30, toward the drum head 45, causing beater 43, to strike the head.However, when the toe end 23, of the pedal is pressed down, the link 26,draws lever 29, down rotating shaft 30, in an opposite direction whichdraws beater 43, away from the drum head and causes beater 44, to strikethe same (see Figure 2). Thus the same rocking motion of the footformerly producing one beat on the drum with my device causes two beatsresulting in one half the foot work required for two beats and thealternate use of separate sets of muscles of the leg and foot, wherebymuscle strain and tiring of the leg and fatigue of the operator is verygreatly relieved, especially in the performance of modern dance music inwhich most of the time four complete beats per measure of music isrequired on the bass drum, which in fast time is difficult to accomplishand very tiring.

In Figure 4 of the drawings I illustrate a modification of the action41, in which the shaft 48, is such that the beaters 49 and 50, are bothsupported in upright position whereby the drum head may be struckadjacent the same point or at its central portion. To obtain this resultthe shaft 48, is in two sections 49 and 50, and to the inner portion 5|,of section 49, is fixed a, bevel gear 52, which drives a transmissiongear 53, which in turn operates gear 54, fixed on the shaft section 50,whereby when link 55, is operated in either direction the sections 49and 50, of the shaft 48, will be rotated in opposing directions causingone beater to strike the drum while the other beater moves away from thedrum head.

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawings.Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size and rearrangement of details and parts such ascome within the purview of the invention claimed may be resorted to, inactual practice, if desired.

Having now described my invention that which I claim as new and desireto procure by Letters Patent is:

1. A double-action bass drum pedal comprising a rockable pedal, a shaft,heaters carried by said shaft, a lever carried by the shaft, a linkconnecting said pedal to said lever, a spring control for said shaft,means for adjusting the action of said shaft, said shaft including apair of alignedsections having spaced inner end portions, a drive gearcarried by the inner end portion of one of the sections, a driven gearcarried by the inner end portion of the remaining section, and meansoperatively connecting the driven gear to the drive gear for rotation ofsaid sections in an opposite direction.

2. A double-action bass drum pedal comprising a rockable pedal, a shaft,heaters carried by said shaft, a lever carried by the shaft, a linkconnecting said pedal to said lever, a spring control for said shaft,means for adjusting the action of said shaft, said shaft including apair of aligned sections having spaced inner end portions, a beveleddrive gear carried by the inner end of one of said sections, a beveleddriven gear carried by the inner end of the remaining section andoppositely disposed relative to the drive gear, and a transmission gearengaging said drive gear and said driven gear.
